What optimizaton flags should i use (g++-4.3.3,Linux,Core2Duo)?


Hello all,

i am playing around with g++-4.3.3 on Ubuntu Linux. The project i am working does a lot of floating point arithmetic (based on double variables). The testplattform i use, is a intel core 2 duo processor. So what optimization flags are good for this plattform? Currently i am using -O3 -funroll-loops, but there are a plenty other. 

Thanks in advance!

Best regards

Ettl Martin
